That's due to margins.  If you change the margins in page setup, the
rulers will go to normal A4 paper.  The centimeters are real
centimeters.

You can set the grid explicitly in the Diagram Properties dialog, just
turn off dynamic grid and set the grid to 0.1x0.1.

The latter would be a problem with the dynamic grid code.  Doesn't seem
to adjust along with the shown grid.
